1. Functional Block Diagram FIG. 1 shows a functional block diagram of a grouping device according to one embodiment of the present invention. The recording unit 2 records a file 6 to which a tag 4 is attached. A hierarchical structure 8 of the tag 4 is also recorded.

  Based on the hierarchical structure 8 of the tag 4 recorded in the recording unit 2, the hierarchical display unit 10 displays the virtual folder associated with each tag on the display unit 12 in a hierarchical manner. The selection means 14 selects one of the displayed virtual folders according to a user operation. The file display means 16 has all the tags of the selected virtual folder (referred to as selection tags) and tags in a higher hierarchy than the selected tags, and all tags in a lower hierarchy than the selected tags. No files to extract. Further, the file display unit 16 displays the extracted file on the display unit 12 as belonging to the selected virtual folder.

  In this way, file grouping by hierarchical tags can be performed by an intuitive operation in the same way as when managing files by a normal hierarchical folder.

2. Hardware Configuration FIG. 2 shows a hardware configuration of a grouping apparatus according to an embodiment. A hard disk 22, a touch screen 24, and a communication circuit 26 are connected to the CPU 20. The touch screen 24 displays characters and images and inputs with a stylus pen or a finger. The communication circuit 26 is for connecting to an internet.

  The hard disk 22 stores an operating system 28, a grouping program 30, a tagged file 32, and a tag hierarchical structure 34. The grouping program 30 functions in cooperation with the operating system 28.

  FIG. 3 shows the external appearance of a tablet computer that employs a grouping device. A power switch 36 is provided below the touch screen 24.

3. Grouping program processing
3.1 File List Display Processing FIG. 4 shows a flowchart relating to hierarchical display processing in the grouping program. When hierarchical display is instructed by a user operation, this hierarchical display process is executed.

  FIG. 6 shows files recorded on the hard disk 22. Image data of each page is recorded as the contents of the file. Each file is identified by a file name. Each file has a tag. For example, the tag “task” is attached to the file “hobby”.

  FIG. 7 shows an example of a tag hierarchical structure 34 recorded on the hard disk 22. In FIG. 7, data indicating the name of the tag and its hierarchy is shown. The tag “Idea” has a hierarchy “1” and is a single numerical value, which indicates that it is immediately below the root hierarchy. The tag “PR” is the same level as the tag “Idea”. The layer “2” is also indicated by a single numerical value.

  The tag “Tiny.note” has a hierarchy “1-1” and is two numerical values separated by “−”, indicating that it is in the second hierarchy. Further, since “1” is shown before “−”, it can be seen that the tag is directly under the “idea”. The same applies to other tags. Note that the method of expressing the hierarchy is not limited to this example, and various methods can be used.

  In step S <b> 1, the CPU 20 acquires the tag hierarchical structure 34 recorded on the hard disk 22. The CPU 20 displays the hierarchical structure of the virtual folder corresponding to each tag as a diagram on the virtual folder display unit 40 of the touch screen 24 based on the acquired tag hierarchical structure (step S2). FIG. 8 shows an example of the display. Here, since it is an initial display, the selection mark 44 is displayed in the root virtual folder.

  In this embodiment, files grouped in the virtual folder selected in the virtual folder display unit 40 are displayed in the file list display unit 42.

  Next, the CPU 20 displays the tag of the selected virtual folder and its upper tag on the upper part 46 of the file list display unit 42 (step S3). Here, since it is an initial display and no virtual folder is selected, only the root tag (in fact, such a tag does not exist but is done in this way for convenience) is displayed.

  The CPU 20 displays an icon 48 for creating a new file on the file list display unit 42 (step S4). Next, the CPU 20 displays a virtual folder immediately below the currently selected virtual folder (here, “root”) on the file list display unit 42 (step S5). Here, the virtual folders 50 and 52 of “Idea” and “PR” immediately under “Route” are displayed.

  Next, the CPU 20 extracts a file to which all of the tags of the selected virtual folder and tags higher than that are attached (step S6). Here, the virtual folder “root” is selected, and there is no corresponding tag. Therefore, all files are extracted.

  Further, the CPU 20 removes the file with the tag corresponding to the virtual folder immediately below from the extracted file (step S7). Here, the files with the tags “Idea” and “PR” are removed. In FIG. 6, the files “Edison”, “Rotation Function”, “Stereoscopic View”, “Stereo”, and “Virtual Drive” are removed, and only the file “Hobby” is left as an extracted file.

  The CPU 20 displays the first page of each extracted file as a thumbnail on the file list display unit 42 together with the file name. Here, the first page of the file “hobby” is displayed as the thumbnail 54.

  Next, the CPU 20 displays a tag other than the tag displayed on the upper portion 46 in the vicinity of the thumbnail 54 for each of the extracted files (step S10). Here, a tag 56 of “task” is displayed. As described above, initial hierarchical display of files and tags is performed.

  In the screen of FIG. 8, it is assumed that the user selects the virtual folder “new function” with a stylus pen or the like. In response to this, the CPU 20 sets the selected virtual folder as the selected virtual folder (step S11a), and executes step S1 and subsequent steps again.

  CPU20 acquires the hierarchical structure of the tag shown in FIG. 7 (step S1). Subsequently, as shown in FIG. 9, the CPU 20 displays the virtual folder on the virtual folder display unit 40 (step S2). At this time, the selected virtual folder is displayed with a mark 60 indicating that it has been selected.

  Subsequently, the CPU 20 displays a tag corresponding to the selected virtual folder and a higher-order tag on the upper part 46 of the file list display unit 42 (step S3). Here, “new function”, “Tiny.note”, and “idea” are displayed.

  Next, the CPU 20 displays an icon 48 for creating a new file on the file list section 42 (step S4). Further, the virtual folder immediately below the selected virtual folder “new function” is displayed on the file list display unit 42 (step S5). Here, the virtual folder 62 of “MTG result” is displayed.

  The CPU 20 extracts a file to which all of the tags of the selected virtual folder and the higher-order tags are attached (step S6). Here, the files with the tags “new function”, “Tiny.note”, and “idea” are extracted. Therefore, in the case of FIG. 6, the files “rotation function”, “stereoscopic view”, “stereo”, and “virtual drive” are selected.

  Next, the CPU 20 removes the file with the tag immediately below the tag of the selected virtual folder from the extracted files (step S7). Here, the file with the tag “MTG result” directly under the tag “new function” is removed. Therefore, the file “stereo” to which “MTG result” is attached is removed from the files “rotation function”, “stereoscopic view”, “stereo”, and “virtual drive”. As a result, “rotation function”, “stereoscopic view”, and “virtual drive” are extracted as files belonging to the virtual folder “new function”.

  In this embodiment, when a file belonging to the selected virtual folder is displayed, the file with the tag immediately below is not displayed. This is because a file with a tag lower than the tag of the selected virtual folder is displayed as belonging to the lower virtual folder.

  For example, in FIG. 9, the thumbnail of the file “stereo” (see FIG. 6) is not displayed on the file list display unit 42. In this state, when the virtual folder 62 is selected by a user operation, a thumbnail of the file “stereo” belonging to the “MTG result” virtual folder is displayed on the file list display unit 42. In this way, when a file belonging to a virtual file is displayed, a file belonging to a lower virtual file is not displayed to facilitate intuitive understanding.

  In this embodiment, if the condition is satisfied, one file may be displayed as belonging to a plurality of virtual files. For example, in FIG. 9, the file “stereoscopic view” is displayed as belonging to the “new function” virtual folder 60 and is also displayed as belonging to the “task” virtual folder 61. In this way, although displayed in two virtual folders, there is only one file as its entity.

  The hierarchy display process has been described above. In this embodiment, all files can be displayed in a list regardless of the tag hierarchy. By clicking the list 90 of the virtual folder display unit 40 in FIG. 9, the CPU 20 displays thumbnails of all files on the file list display unit 42. At this time, the tag attached to each file is displayed in the vicinity of each thumbnail. For example, in the case of the file “stereoscopic”, not only “task” tags but also “idea”, “Tiny.note”, and “new function” tags are displayed.

  In this embodiment, a new virtual folder corresponding to a new tag can be generated at an arbitrary location on the virtual folder display unit 40 by a user operation. Moreover, a tag can be attached to each file by a user operation.

3.2 File Editing Process When the user touches and releases the new file creation icon 48 on the screen of FIG. 9, the CPU 20 performs a new file creation process. 10a and 10b show flowcharts of new file creation processing in the grouping program.

  In step S21, the CPU 20 displays a file editing screen on the touch screen 24. An example of the file editing basic screen is shown in FIG. The pattern of the icon 66 is “pen”, indicating that the current mode is the edit mode.

  In this state, the user can move a stylus pen, a finger, and the like, and input characters 70 and a picture on the input screen 68 using the locus. In addition, when the icon 66 obstructs the input, it can be moved to an arbitrary position.

  When the icon 66 is touched in the state of FIG. 11 (step S22), the CPU 20 displays a file edit change screen as shown in FIG. 12 (step S23). The pattern of the icon 66 is “pen”, indicating that it is still in the edit mode. Around the icon 66, an eraser icon 72 for erasing the drawing and icons 74a, 74b, 74c, 74d, 74e for selecting the color, thickness and shape of the pen tip are displayed.

  The currently selected icon is surrounded by a bold line. In FIG. 12, the icon 74e is the currently selected pen tip. When changing the pen tip or using the eraser function, the user selects a corresponding icon.

  When the browse button 76 is touched in the state of FIG. 12 (step S24), the CPU 20 displays the file browsing screen shown in FIG. 13 (step S25). On the file browsing screen, characters and figures cannot be entered. Therefore, there is no possibility that unnecessary drawing may be performed when the screen is touched to zoom in or out or to send a page by pinch-in or pinch-out operations to view the contents of the file. In this file browsing screen, the pattern of the icon 66 is changed to “eyes”.

  When the icon 66 is touched on the file browsing screen of FIG. 13 (step S26), the screen returns to the file editing basic screen of FIG. 11 again (step S21).

  When assigning a name (file name) to the created file, the user touches the title input button 78 on the file edit change screen of FIG. When the title input button 78 is touched, the CPU 20 displays a title input screen (not shown) (step S28). The user touches the keyboard displayed on the title input screen and inputs a file name. When the user touches the input completion button (step S29), the CPU 20 displays the file edit change screen of FIG. At this time, the input file name is displayed at the position of the title input button 78. For example, if the file name “patent” is input, this “patent” is displayed.

  To finish editing the file, the user touches the end button 80 in FIG. When the end button 80 is touched (step S30), the CPU 20 automatically attaches and records the tag of the selected virtual folder to which the new file creation icon 48 belongs and the tag above it to the file. (Step S31). Then, the file editing process ends.

  As a result, the CPU 20 returns to the screen of FIG. A thumbnail 82 of the newly created file “patent” is added. That is, when a new file creation icon 48 is selected and a new file is created, the tag of the selected virtual folder and the higher-order tag at that time are automatically attached to the file.

  In this embodiment, in addition to the tags that are automatically attached as described above, the user can arbitrarily input the tags and give them.

  In the above description, the creation of a new file has been described. The same applies to editing of a created file. In this case, the file to be edited can be opened by touching and releasing the thumbnail displayed on the file list display unit 46.

  In this embodiment, when a thumbnail of the file list display 46 is touched, the thumbnail of each page of the file is displayed. A flowchart of the file opening process is shown in FIGS. 16a and 16b.

  For example, when the user touches a thumbnail of the file list on the screen of FIG. 14, the CPU 20 acquires each page of the file (step S41). For example, when the thumbnail “84” of the file “stereoscopic” is touched with a stylus pen or the like, the CPU 20 acquires the page content of the file “stereoscopic” of FIG.

  Next, the CPU 20 displays the thumbnail of each page on the thumbnail of the file list (step S42). Here, as shown in FIG. 15, the first page thumbnail 86 and the second page thumbnail 88 are displayed above the “stereoscopic” thumbnail.

  As shown in FIG. 15, the CPU 20 displays page feed buttons 90 and 92 (step S43). When the page feed buttons 90 and 92 are touched (when the thumbnail 84 is touched and then slides without touching the thumbnail 84 and touches the page feed buttons 90 and 92) (step S44), the CPU 20 determines the thumbnail of the page. The page is advanced or returned (step S45).

  In the example of FIG. 15, since the contents of only two pages are included in the file, the display is not changed by the page feed buttons 90 and 92. However, if the file contains a large number of pages and the previous page cannot be displayed, the page is turned and returned as described above and displayed.

  Next, the CPU 20 determines whether or not the touch is interrupted with the thumbnails in the file list (step S46). For example, after the touch is performed on the thumbnail 84 in FIG. 15, when the touch is released at that position, it is determined that the touch is interrupted at the thumbnail of the file list. In this case, the CPU 20 opens and displays the file with one page as an initial display (step S47).

  Further, the CPU 20 determines whether or not the touch is interrupted with the thumbnail of the page (step S48). For example, if it is determined that the touch is interrupted on the two-page thumbnail 88 of FIG. 15, the CPU 20 opens and displays the file with the second page as the initial display page (step S49).

  Therefore, the user can check the contents of each page with the thumbnail and open the file with the desired page as the initial page.

3.3 Tag Operation Processing In this embodiment, when a virtual folder is operated, a tag is automatically operated correspondingly.

  FIG. 17 shows a flowchart of the tag operation when the virtual folder is deleted. For example, it is assumed that the “new function” virtual folder 60 is deleted by a user operation on the screen of FIG.

  At this time, the CPU 20 performs a display on the screen for selecting whether the file of the virtual folder is a target (process (a)) or all files (process (b)) (step (b)). S51). The user selects one with a stylus pen or the like. The CPU 20 determines which one has been selected by the user (step S52).

  When the process (a) is selected by the user, the CPU 20 cancels the deleted tag and the lower tag for the deleted virtual folder and the files belonging to the lower virtual folder (step S53). . Note that tag release means deleting a tag recorded as shown in FIG. 6 (the actual file is not deleted). Here, the tags “new function”, “sound function”, “stereoscopic view”, “virtual drive”, “patent”, and “stereo” belonging to the “new function” virtual folder and the “MTG result” virtual folder are added. "MTG result" is canceled. Therefore, the display screen is as shown in FIG.

  When the process (b) is selected by the user, the CPU 20 releases the deleted tag for all the files (step S54). Here, the tag “new function” is canceled from all the files with the tag “new function”.

  In the above embodiment, the user is allowed to select which of the processes (a) and (b) is to be executed. However, any predetermined process may be automatically executed.

  FIG. 19 shows a flowchart of the tag operation when the virtual folder is moved. For example, in the screen of FIG. 14, it is assumed that the “new function” virtual folder 60 is moved to a lower hierarchy of the “public information” virtual folder 59 as shown in FIG. In this embodiment, the virtual folder can be moved by dragging. When the virtual folder is moved, the virtual folder and its file, the lower virtual folder and its file are moved.

  At this time, the CPU 20 displays on the screen for selecting whether to reattach the tag (process (a)) or whether to add the tag (process (b)) (step S61). The user selects one with a stylus pen or the like. The CPU 20 determines which one has been selected by the user (step S62).

  When the process (a) is selected by the user, the CPU 20 determines the virtual folder at the original position and the virtual folder at the higher level than the virtual folder for the file belonging to the lower level than the virtual folder. Remove the tag corresponding to. Further, a tag corresponding to the virtual folder at the position of the movement destination and the virtual folder belonging to a higher hierarchy than the virtual folder is assigned (step S63). That is, the tag at the original position is canceled and the tag at the new position is assigned.

  Here, the tags of “Idea” and “Tiny.note” at the original position are deleted, and the tag of “PR” at the new position is given. As a result, a display screen as shown in FIG. 20 is obtained.

  When the process (b) is selected by the user, the CPU 20 assigns tags corresponding to the virtual folder at the movement destination position and the virtual folder belonging to a higher hierarchy than the virtual folder while leaving the already assigned tag as it is. (Step S64). That is, a tag at a new position is added.

  Here, a tag of “PR” at a new position is additionally provided.

  In the above embodiment, the user is allowed to select which of the processes (a) and (b) is to be executed. However, any predetermined process may be automatically executed.

  When the virtual folder is copied to another location, the virtual folder and its file, the lower virtual folder and its file are copied to another location. At this time, the CPU 20 adds and adds tags corresponding to other locations in addition to the tags corresponding to the original locations to these files (if they overlap, they are not added).

  In the above, tag operation when deleting a virtual folder has been described. In this embodiment, even when the file itself is to be deleted, one of the following processes (a) and (b) is selected.

  When the process (a) is selected, the entity of the file is deleted.

  When the process (b) is selected, the tag corresponding to the currently selected virtual folder is deleted without deleting the file. For example, when the “stereoscopic” file 84 is deleted on the screen of FIG. 14, the “new function” tag attached to the file 84 is deleted.

  In the above embodiment, the user is allowed to select which of the processes (a) and (b) is to be executed. However, any predetermined process may be automatically executed.

3.4 Page Movement Processing FIG. 21A shows the relationship between the page display area of the file and the entire page area. In this embodiment, not only the entire page but also a part of the page can be enlarged and displayed. For example, in the case of FIG. 21A, the area of the entire page is 100, and a part thereof is displayed in the display area 102 of the touch screen 24.

  In this state, when the user performs a page turning operation (such as touching a predetermined icon), the CPU 20 displays the next page. At this time, conventionally, when the next page is displayed, as shown in FIG. 21B, the display is performed at the magnification and position set by default. The same was true when creating a new page.

  For example, when creating a new page, it is impossible to grasp that the magnification or the display position is different from the page that was edited immediately before. This is because the new page is blank.

  Therefore, in this embodiment, when the page is moved, the CPU 20 takes over and displays the display parameters (magnification, position, etc.) of the page before the movement as it is. Therefore, a display as shown in FIG. 22 is made. In addition, even in the case of a new page, since the parameters are inherited, the drawing process is facilitated.

3.5 Calligraphy Pen In this embodiment, when inputting with a stylus pen or a finger, the trajectory can be drawn like a calligraphy pen. FIG. 23 shows the shape of the tip of a virtual calligraphic pen used in this embodiment. The nib parameters are set by the long side a, the short side b, and the angle c. The angle c is an angle with the reference line ST (in this embodiment, a line parallel to the upper side and the lower side of the display area). These parameters are recorded in the hard disk 22 as a parameter table as shown in FIG.

  When the user touches the screen of FIG. 11 with a stylus pen or the like, the CPU 20 draws a rectangle shown in FIG. Further, when the user moves the stylus pen while touching the screen, the locus of this rectangle is drawn. FIG. 25 shows a flowchart of this drawing process.

  CPU20 draws the locus | trajectory which the user input as a locus | trajectory of the point d of FIG. 23 (step S71). Next, the CPU 20 draws trajectories of other vertices e, f, and g based on the parameters a, b, and c in FIG. 24 (step S72). However, here, these trajectories are not drawn as visible lines, but are drawn in the calculation. Further, the CPU 20 fills the figure enclosed by these trajectories with a predetermined color and a predetermined transparency (set by parameters). The above processing is repeatedly executed.

  With the above processing, for example, as shown in FIG. 26A, a line is drawn along the trajectory.

  In this embodiment, the long side a, the short side b, and the angle c can be changed on the parameter setting screen. For example, when the length of the long side “a” is shortened, the whole is drawn thinly as shown in FIG. When the angle c is increased, the horizontal line is drawn thick as shown in FIG. 26C. Further, when the short side b is lengthened, the whole is drawn thick as shown in FIG. 26D.

  In this way, by changing the parameter, it is possible to change the expression by the drawn line. In this embodiment, the CPU 20 not only draws with the set parameters, but also allows the parameters to be changed after drawing the trajectory (the same applies to the following embodiments).

  In the above embodiment, the vertex d is used as the reference point, but other vertices e, f, and g may be used, or a rectangular center point e may be used.

  In addition, by setting parameters, it is possible to select whether to increase the density of the portion where the trajectory overlaps (see FIG. 27A) or the same density (see FIG. 27B). The CPU 20 executes one of the processes according to the parameters.

  Further, the drawing color (drawing density) of the surface 120 and the surface 122 in the pen tip of FIG. In this case, as shown in FIG. 29, the CPU 20 preferentially paints the color of the front surface with respect to the locus α. For example, in the case shown in FIG. 29A, since the surface 122 is the front surface with respect to the trajectory α, the color set on the surface 122 is used for filling with priority over the color set on the surface 120. . That is, the color of the surface 120 is used in a portion where the locus by the surface 120 and the locus by the surface 122 overlap.

  For example, drawing as shown in FIG. 28A is performed. Here, it is assumed that the surface 120 is set in red (shown in dark color in the figure) and the surface 122 is set in green (shown in light color in the figure). It is shown that the drawing color differs depending on the direction of the locus. In this embodiment, the short side b of the nib is set to zero.

  Unlike the above, in the continuous trajectory, the first moving direction of the trajectory is given priority to the surface 120, and on this basis, when the moving direction is opposite to the surface 120, the surface 122 is given priority. Also good. In this case, even if the locus is the same as that in FIG. 28A, the drawing as shown in FIG. 28B is performed.

  Whether to perform drawing as shown in FIG. 28A or drawing as shown in FIG. 29A can be set by a parameter. Also, as with other parameters, after drawing, the parameters can be changed and redrawing can be performed.

  In this embodiment, in the pen tip of FIG. 23, drawing can be performed with any one of the four surfaces as a main surface by parameter setting. For example, the surface 122 in FIG. 23 can be set as red with the main surface as the main surface, and the other three surfaces can be set as black.

  As shown in FIG. 30A, the CPU 20 preferentially displays the one drawn later in the portion where the trajectories overlap. In the figure, the trajectories α1, α2, and α3 are drawn in this order.

  Unlike the above, in the portion where the trajectories overlap, the main surface may be given priority over the other surfaces regardless of whether the trajectory is drawn later or drawn earlier. In the figure, portions 130, 132, etc. are places where the main surface is displayed with priority.

  Note that whether to perform drawing as in FIG. 30A or drawing as in FIG. 30A can be set by a parameter. Also, as with other parameters, after drawing, the parameters can be changed and redrawing can be performed.

  Further, as shown in FIG. 31A, a line may be drawn by a vertex of a pen point rectangle to display a frame line. In the example of FIG. 31A, the frame line is displayed in black, and the entire locus is displayed in yellow. Further, the length of the short side is set to zero.

  Further, as shown in FIG. 31B, the drawing can be performed so that the color changes according to the movement of the locus, that is, with a gradation.

  The display of the frame and the presence / absence of gradation can be set or changed in advance by parameters or after drawing.

  In each of the above embodiments, when different colors are used, different colors having the same color density may be used.
